How long does it typically take a RT to get to full size? Im looking at a harness and they arent cheap for what im going to get so im trying to decide if i should just wait and suffer with the one we have for now or what.

yea i have a harness, i was just going to buy a fancy one but it looks like it would be a waste of money until she gets bigger. I was going to order a puppia step on one. Pixel is not happy about it going over her face.
